Hospital hygiene refers to the practices and measures taken to prevent and control infections within healthcare settings, such as hospitals, clinics, and nursing homes. This includes proper hand hygiene, environmental cleaning and disinfection, sterilization of medical equipment, and implementation of infection control protocols. Hospital hygiene is critical in preventing the spread of healthcare-associated infections (HAIs) among patients, healthcare workers, and visitors. HAIs can lead to prolonged hospital stays, increased healthcare costs, and even death in some cases. Therefore, maintaining a high standard of hygiene in healthcare facilities is essential to ensure the safety and well-being of patients and staff. Research in hospital hygiene aims to identify effective strategies and interventions to reduce the incidence of HAIs and improve overall hygiene practices in healthcare settings. This may involve studying the effectiveness of different cleaning and disinfection methods, evaluating the impact of hand hygiene education programs, and assessing the use of antimicrobial coatings on hospital surfaces. Overall, research in hospital hygiene plays a key role in advancing patient safety and quality of care in healthcare settings by identifying best practices for infection prevention and control.
